Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003940983
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

Inspection and AdjustmentINFOID:0000000003811312
INSPECTION
Pedal Stroke
1. Operate the parking brake pedal with a force of 196 N (20 kg, 44 lb). Check that the pedal stroke is within
the specified number of notches. (Check it by listening to the clicks of the ratchet.)
2. When brake warning lamp turns ON, check that the pedal stroke is within the specified number of
notches. (Check it by listening to the clicks of the ratchet.)
Inspect Components
• Check each component for installation condition such as looseness.
 Check the device assembly for bend, damage and cracks. Replace if necessary.
 Check the cables for wear, damage and cracks. Replace if necessary.
 Check the parking brake switch, and replace it if necessary. Refer to BRC-41, "
Diagnosis Procedure" (with-
out VDC), BRC-124, "
Component Inspection" (with VDC).
ADJUSTMENT
1. Remove rear tires.
2. Fix the disc rotor using wheel nuts.
3. Release the parking brake pedal (1) by turning the adjusting nut
(2) with a deep socket wrench and loosening the cable.
4. Remove the adjusting hole plug from the disc rotor. Turn the
adjuster (1) in the direction (A) as shown in the figure using a
suitable tool until the disc rotor is locked.
5. Turn back the adjuster 5 or 6 notches from the locked position.
6. Rotate the disc rotor to check that there is no drag. Install the
adjusting hole plug.
7. Adjust the cable with the following procedure.
a. Operate the parking brake pedal with a force of 490 N (50 kg,
110 lb) for 10 strokes or more.
b. Adjust the parking brake pedal stroke by turning the adjusting
nut with a deep socket wrench.
CAUTION:
Never reuse the adjusting nut if the nut is removed.Standard
